Man, 51, dies walking his dog along Cabrillo Beach in San Pedro

A 51-year-old man died while walking his golden retriever on Cabrillo Beach in San Pedro Tuesday morning, authorities said.

The man was last seen alive at about 6 a.m. by another dog walker in the 3700 block of Stephen M. White Drive, Los Angeles Police Department Lt. John Pasquariello said. The two waved at each other. About a half hour later, at 6:30 a.m., someone saw the man's body lying at the water line, Pasquariello said. He had died of apparent natural causes. His dog stayed by his side for hours as police arrived and investigated the scene. At one point, the dog was seen lying by the man's body.

Police took the dog to the man's San Pedro home, where he lived with his wife and children, Pasquariello said.
